With no disrespect to you, 100 hours really isn't a lot for people that don't play much.
Having to rush the Sinnoh content is more difficult for those that don't have the help. Hannah is quite difficult for casual players to beat.
The requirements for Darkrai are extremely fair and I don't think it needs to be lowered any more. Otherwise this account (not my main-with only 7 hours) could rush the regions and get a super strong legendary. Just no.
Saying that an hour requirement should be a requirement for a pokemon? are you serious? thats like saying "He has been playing for 500 hours, Lets give him 5 million pokedollars. I understand if it can be used to beat the game but if you have already beaten all the elite fours up to how far everyone else is, then what is the difference if you have played 50 hours or 500 hours. And since its only available till the 5th I agree that it is stupid
